[Premium-Rx] Differences between WJ-8716 and WJ-8716A

[Terry O']

The internal records show four versions of the 8716.  They do not show 
an 8716A, just a plain, and dashes -1, -2, & -3.

The 8718 records may provide insight as they are same radio w/o the RFI 
shielding.  There are 32 versions of the 8718, of which 5 were "A".   
The 8718A notes the following changes from the 8718:  "battery is on 
back, line audio level is on front, automatic self-testing."

8716 production predates the 8718A for all versions except the 8716-3.  
The 8716-3 arrived three years after the 8718A was developed.  It may 
have characteristics of the 8718A or not, depending on the wishes of the 
agency that ordered it.  It differs from all the other 8716s in that the 
widest IF was 10 kHz instead of 16 kHz.

In any event the records do not show any radio produced as an 8716A.

Have you seen a nomenclature plate that says 8716A?  If so, I'd love to 
see a picture of it.
